ARGYNNIS I?. 



black scales; the submarginal lunules are yellow and the spaces between the mar- 

 ginal lines 2>artially so, giving the effect of a double row of marginal spots on sec- 

 ondaries; in the cell of pi'iraaries two transverse yellow stripes and nearer base a 

 stripe composed of greenish scales ; under side similar to male except that the yel- 

 low is more decided and not golden and the margins- of both wings as well as the 

 apical portion of ^^rimaries much irroratcd with black; the subapical silver spots 

 are also on a black ground; secondaries have the basal portion much obscured by 

 a greenish-brown tint, and much irrorated with black, the belt between the two 

 outer rows of silver spots being clear yellow and immaculate. 



From 5<?, 2 2, brought from Arizona by the Exploring Expedition under 

 Lieut. Wheeler, in 1871, but with no further intimation of their locality. The 

 original specimen from which the descrijrtion of the species was drawn was received 

 by me in 1862, through the Smithsonian, and was labelled "Bitter Root Mountains." 

 Until the present year (1872) it has been an unique in my collection and, so far as 

 I know, not found in any other. But the species is so superb an one that I have 

 not hesitated to redraw the j^late. It is allied to Leto in many respects, in the 

 general a2ipearance of the upper side of the male, and in the colors of the female. 

 But in the shape of the spots the female bears a curious resemblance to Diana. I 

 regret that I am able to add nothing of its history.
